Guardians vs Rays MLB Betting Preview

Cleveland Guardians Betting Preview

Cue the Undertaker meme.

The Cleveland Guardians looked destined for an ALDS exit after dropping the first two games against division rival Chicago White Sox on their home turf. But in Game 3, the Guardians went into Chicago and dominated. Fueled by a mid-series resurgence from Jose Ramirez, Cleveland rallied to complete the reverse sweep. Ramirez’s shoestring home run in Game 5 provided the only offense in an eventual 2-0 victory.

If Ramirez can maintain this form, the Guardians offense will be a pest to deal with. Battling injuries throughout the season, Ramirez hit just 12 home runs and posted his lowest on-base percentage (.320) since 2015.

This roster is the Island of Misfit Toys. Outside of Ramirez, who struggled for much of the year, there aren't many household names. Similar to Tampa Bay, this isn't an offense built to outslug opponents.

Cleveland's lack of power led to the mid-season acquisition of Jo Adell. Not only has Adell been a valuable addition against left-handed pitching, but he's arguably been the Guardians' second-best offensive weapon this postseason.

As a team, the Guardians finished the second half with a 103 wRC+, good for 10th in MLB. This is an offense that makes opposing pitchers work in the zone and rarely beat themselves with strikeouts. They ranked second in MLB with an 18.5% strikeout rate during that span.

After an extended series that forced Gavin Williams and Patrick Messick to pitch on short rest, Cleveland hands the ball to left-hander Foster Griffin in Game 1.

Like Adell, Griffin arrived at the trade deadline. He's struggled to find his footing in Cleveland, posting a 5.19 ERA across nine starts. However, he delivered when it mattered most in Game 3 against Chicago, tossing 2.2 innings of one-run ball while striking out seven.

One thing worth noting about Cleveland's pitching staff is that manager Stephen Vogt wasn't afraid to make a quick call to the bullpen during the divisional series. Griffin could be on for a quick hook here as Vogt not only has a dominant bullpen, but Tanner Bibee and Joey Cantillo ready in long relief if needed. 

While there are question marks surrounding Cleveland's starting rotation, its bullpen ranks among MLB's best. The Guardians finished the second half fourth in xFIP (3.76) and fifth in left-on-base rate (77.1%), consistently limiting damage when opponents threatened.

Cade Smith is arguably the best closer in baseball, finishing the regular season with 41 saves and a 1.95 ERA. The flamethrowing right-hander appeared in all five games against Chicago, tossing 6 2/3 innings of one-run ball while striking out 11. His 36.3 K% ranks in the 99th percentile of all qualified pitchers. 

Tampa Bay Rays Betting Preview

Unlike their championship-series counterparts, the Tampa Bay Rays cruised past the New York Yankees and remain undefeated this postseason. Tampa allowed just five runs across its three games, setting the tone with a dominant pitching staff and a gritty, opportunistic offense.

The well-rested Rays turn to Drew Rasmussen in Game 1 for the second straight series. Rasmussen was nearly unhittable against the Yankees, allowing his first hit — an Austin Wells double — with two outs in the eighth inning. Wells was thrown out attempting to stretch it to a triple, and Rasmussen finished with 10 strikeouts in the win.

Rasmussen is one of the most underrated arms in baseball. He doesn't get the recognition of other aces, but he pairs elite control with a 110 Stuff+. Since joining the Rays in 2021, Rasmussen has posted a 2.90 ERA or better in each of the last five seasons.

The 31-year-old is also split-proof, holding right-handed hitters to a .191 average and .510 OPS. Lefties haven't fared much better, hitting .205 with a .568 OPS against him.

If there's a weakness in Rasmussen's profile, it's his 25.1% whiff rate, the only metric in which he ranks outside the top half of qualified pitchers. Even then, he's just barely below average, sitting in the 49th percentile.

Tampa Bay's bullpen is above average, though there are some vulnerabilities if opponents can force an early exit from the starters. The Rays posted a 4.05 xFIP in the second half, ranking 10th in MLB. They've struggled to keep the ball in the yard during that span, allowing 1.25 HR/9, but have issued the second-fewest walks in baseball, helping limit the damage.

That said, if Tampa's starters work deep into games, opponents are in trouble. Bryan Baker has established himself as one of MLB's best closers, recording 41 saves with a dominant 1.44 ERA. He closed out all three games against the Yankees, allowing just one walk across three scoreless innings.

Behind Baker, southpaw Cam Booser has been nothing short of phenomenal, posting a 1.98 ERA across 41 innings. Kevin Kelly has also provided some much-needed stability in the bullpen.

The offense is headlined by none other than Junior Caminero, who needs no introduction. The 23-year-old is a bona fide superstar coming off back-to-back 40-plus-homer seasons.

As a whole, however, Tampa's offense ranked just 14th in wRC+ (100) in the second half. Even with Caminero, this isn't a team built to outslug opponents. Instead, the Rays put the ball in play, apply pressure on the basepaths and force opposing defenses to execute. We saw how that approach played out against the Yankees, whose defense struggled to keep up with Tampa's quick, gritty style.

This is an aggressive team that never quits, and the Rays enter this series as the favorites to advance for good reason.

Guardians vs Rays Pick, Betting Analysis

While this is a seven-game series and pitchers may have longer leashes, I still don't expect Griffin to pitch deep into this ballgame. Could he get through the order twice? Possibly. But by the time Junior Caminero comes to the plate for a third time, Griffin will likely be watching from the dugout steps.

As mentioned earlier, the Rays are a pesky, contact-heavy lineup. They rarely strike out, and that's especially true against left-handed pitching with an 18.1% strikeout rate, No. 1 in all of MLB.

While Griffin struck out seven White Sox hitters in his first postseason appearance, it's worth remembering that it came against Chicago. They were fifth-worst in the second half in strikeout rate. I don't expect him to replicate that success against Tampa.

I'm happy to fade the left-hander and back the under on his strikeout prop (3.5). The Rays hold the advantage in both starting pitching and offense in Game 1 and should have little trouble taking the opener despite the extended layoff.

I will also be adding a small bet on Junior Caminero to hit a home run at +475. The superstar has a 152 wRC+ against left-handed pitching and grades out well against Griffin's main pitches: the cutter (+2 run value) and fastball (+8 run value). Could he be pitched around? Yup. But I'll take my chances.

Pick: Foster Griffin Under 3.5 Strikeouts(-104, FanDuel; Play to -115)
